See the book I recently published:
Hildegard L.C. Tristram, ed., *The Celtic Englishes*, Heidelberg
1997: Carl Winter Universitaetsverlag
The book contains the proceedings of the Colloquium on the "Celtic
Englishes" which I organised at the University of Potsdam in September 1995
(CE-I). I am doing a follow-up Colloquium this coming September (CE-II).
